Ema, a literature club girl who makes doujinshi with her friends, encounters a tragedy in an alley after parting ways with them. A man's wet fingertips trace her white skin. Her legs are roughly spread apart, and she is filled with fear. Yet, her vagina, contrary to her fear, welcomes the frenzied, pleasure-soaked penis. Her softly swelling breasts bounce with the piston-like motion. Unconsciously, a sigh escapes. A woman's sexuality, felt without knowledge.
